The repertoires below offer you three ways of playing against most of the semiopen defences, and also tell you what to do against some of the less common lines after 1. e4 e5 2. Nf3.
The three approaches are:
Fast attacking game with pieces
Slower attacking game with f4
King's Indian Attack with g3
Which you choose will depend on what sort of player you are. It may also depend on what you hope to play after 1. e4 e5.
Fast attacking game with pieces 
Giuoco Piano (my main recomendation for junior players) or Scotch Game 
Slower attacking game with f4 
Vienna Gambit or King's Gambit) 
King's Indian Attack with g3 
KIA with 1. e4 e5 2. Nf3 Nc6 3. g3 or in the Vienna 1. e4 e5 2. Nc3 Nc6 3. g3 
Sadly, the KIA lines have no real force and are not good lines to adopt against 1...e5. But the point is, how well does your chosen repertoire fit together? Once I used to play the following lines, together with the King's Gambit:
Alekhin 1. e4 Nf6 
Chase variation 1. e4 Nf6 2. e5 Nd5 3. c4 Nb6 4. c5 Nd5 5. Bc4 e6 6. Nc3 
CaroKann 1. e4 c6 
PanovBotvinnik Attack 1. e4 c6 2. d4 d5 3. exd5 cxd5 4. c4 
French 1. e4 e6 
Advance Variation 1. e4 e6 2. d4 d5 3. e5 
Pirc/Modern 1. e4 ...d6/...g6 
King's Indian Attack 1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. Nge2 and 5. g3, 6. Bg2 
Sicilian 1. e4 c5 
Chamaeleon Variation 1. e4 c5 2. Nc3 ... 3. Nge2 
This was an awful lot to keep track of, but more importantly, it didn't really combine well. Against the Alekhin I played fast, against the Caro I played medium, against the French and Pirc I played slow; the Panov line is mainline established theory with lots to learn and keep track of, the Chamaeleon is a new and obscure line where you have to think at the board.
Now, I'm sure a better idea, and the right idea, is to play similarly against each opening. For example, if you like gambits and play the Danish Gambit against 1...e5, try and find a gambit against the lot....
Alekhin 1. e4 Nf6 
1. e4 Nf6 2. Bc4 Nxe4 3. Bxf7+ Kxf7 4. Qh5+ g6 5. Qd5+ 
CaroKann 1. e4 c6 
Fantasie Variation 1. e4 c6 2. d4 d5 3. f3 e5 4. Nf3 exd4 5. Bc4 
French 1. e4 e6 
Advance Variation, Milner Barry Gambit 1. e4 e6 2. d4 d5 3. e5 c5 4. c3 Nc6 5. Nf3 Qb6 6. Bd3 
Pirc/Modern 1. e4 ...d6/...g6 
I don't know any gambits for White in the Pirc but against the Modern you can try... the Monkey's Bum! 1. e4 g6 2. Bc4 d6 3. Qf3 Nf6 4. d4 e5 5. Nh3 
Sicilian 1. e4 c5 
Morra Gambit: 1. e4 c5 2. d4 cxd4 3. c3 dxc3 4. Nxc3 or 3. ... Nf6 4. e5 Nd5 5. Bc4 Qc7 6. Qe2 
I think neither the Alekhin line nor the Monkey's Bum are really any good, but at least we're thinking along the right lines, even if this isn't the repertoire we settle on.
Here's a repertoire based on pawn advances and space advantages:
Alekhin 1. e4 Nf6 
Four pawns variation 1. e4 Nf6 2. e5 Nd5 3. c4 Nb6 4. d4 d6 5. f4 
CaroKann 1. e4 c6 
Advance Variation 1. e4 c6 2. d4 d5 3. e5 
French 1. e4 e6 
Advance Variation 1. e4 e6 2. d4 d5 3. e5 
Pirc/Modern 1. e4 ...d6/...g6 
Three Pawns Attack 1. e4 d6 2. d4 Nf6 3. c3 g6 4. f4 
Sicilian 1. e4 c5 
Big Clamp Variation 1. e4 c5 2. d3 (...) 3. f4 
Now, what sort of player are you? Whether you like lively piece attacks, slow pawn advances that you can use to force open lines or more flexible systems, there is a repertoire here for you.
Let's have a look at some variations that fit together.

I simply haven't the courage to take on a repertoire which includes the Open Sicilian, and my experience of playing the Black side of the Sicilian is that not many White club players have either! So I'll leave those lines to you and any time you have to do your own research. I have a feeling it's something you come to study as your chess improves. Analysis and Games
I'll go through each approach in turn, looking at a system to play against each defence.
I'll concentrate more on the example games than the theory, and more on the 'piece attack' lines than the others, because I think that's what you should be playing.
A. Piece attacks against the common halfopen defences
In each of these lines White has a straightforward plan of campaign:
rapid development
keep Black passive
keep lines open if you can
keep an eye out for lightning raids
A1. Piece attacks vs. Alekhin 1. e4 Nf6: 1. e4 Nf6 2. Nc3 d5 3. exd5 Nxd5 4. Bc4
This is not a particularly wellregarded line for White  that is, it is not considered to be a good way to try for advantage at GM level. But it gives you game where you don't have to learn much sharp theory and you are playing the sort of game you like. It has also been responsible for some amusing miniatures:
Ourmet,J  Cierniak,P (1) Paris, 1989
1. e4 d5 2. exd5 Nf6 3. Nc3 Nxd5 4. Bc4 Nxc3 5. Qf3 e6 6. Qxc3 Nc6 7. Nf3 b6

and
Iskov,G  Woge Nielsen,J, it, Kobenhavn, 1989
1. e4 Nf6 2. Nc3 d5 3. e5 d4 4. Nce2 Ne4 5. c3 c5 6. d3 10
You must be prepared, after 1. e4 Nf6 2. Nc3, to play the Vienna or other opening after 2...e5.
After 2...d5 3. exd5 Nxd5 4. Bc4 Black has a choice of moving the knight (4...Nb6, 4...Nxc3) or finding some way to defend it (4...c6, 4...e6):
White's next is easy to find.
5. Bb3 c5
[5... Nc6 6. Qf3 e6 7. Nge2 Be7 8. d3 OO 9. Bf4 Na5 10. Qg3 Bd6 11. Ne4 Nxb3 12. axb3 Bxf4 13. Nxf4

White plays a likelylooking Queen sacrifice.

White has compensation for the sacrificed pawn.
Again, the Qf3 move is strong; Black is obliged to lock in the Bc8.

6... c4 7. Bxc4 Nxc4 8. Qb5+ Nc6 9. Qxc4 Qd4 10. Qxd4 Nxd4 11. Kd1
White is a pawn up and just needs to survive the next few moves to reach a winning endgame.

Black skips to the Queen'sside
10. d4 Be7 11. Be3 Bf6 12. Rad1 Ne7 13. Ne5 Be8 14. Bf4 Nf5 15. Ng6 e5
This central break is the right sort of idea for Black, but goes very wrong here.
16. dxe5 Qxd1 17. exf6 Bc6 18. Qe5 Rd7 19. Rxd1 Rxd1+ 20. Bf1 Nd6 21. Nxh8 Bb5 22. Qxb5 Nxb5 23. fxg7 10
I have spent quite a while on the Alekhin's, not because it's a very common line but
you won't find much on the Bc4 plan in the books
the White plan is exactly what you should be doing in all the recommended lines below.
A2. Piece attacks vs. CaroKann Defence
All the main lines in the books continue:
1. e4 c6 2. d4 d5
and now
3. Nc3 dxe4 4. Nxe4
You may find players who will try and gum the whole position up with 3...g6. tempting 4. e5. You can play 4. h3 but the resulting positions are rather dull If you don't like that idea, try instead
3. Nd2
when 3...g6 can be met by 4. c3, keeping the tension in the centre, and
3...dxe4 4. Nxe4
gives us the starting position from the books.
Black has tried 3...Nf6 e.g.
TalCampomanes, Leipzig Olympiad 1960 [B15]
1. e4 c6 2. d4 d5 3. Nc3 Nf6 4. e5 Nfd7 5. e6 fxe6 6. Bd3 Nf6 7. Nf3 g6 8. h4 c5 9. dxc5 Nc6 10. Qe2 Bg7 11. Bd2 Qc7 12. OOO e5 13. Bg5 Be6 14. Nb5 Qb8 15. h5 gxh5 16.

White places his pieces actively in the hope of forcing ...e6 before the Bc8 escapes.
5. Bc4 Ngf6 6. Ng5 e6 7. Qe2 Nb6
[7... h6 8. Nxf7 Kxf7 9. Qxe6+ Kg6 10. Bd3+ Kh5 11. Qh3#]
8. Bd3 h6
[8... Qxd4 is too dangerous:
9. N1f3
idea Ne5,Ng5xf7
9... Bb4+ 10. c3 Bxc3+ 11. Kf1 Qc5 12. bxc3 Qxc3 13. Bb2 Qa5
White has great play for the pawn]
9. N5f3 c5 10. dxc5 Bxc5 11. Ne5 Nbd7 12. Ngf3 OO 13. Bd2 Nxe5 14. Nxe5 Bd4
[14... Qd5 15. OOO Qxa2 16. c3]

28. Rxf7+ Kd6 29. Rd7+ Kc5 30. Rxb7 10
KirpichnikovLein, 1974]
5. Nxf6+
...and Black has a choice of captures.
A2.2.1 Tartakower Variation, 5... exf6
This is a dull line for Black. The most straightforward attacking line against it is
6. c3 Bd6 7. Bd3 OO 8. Ne2 Re8 9. Qc2 g6 10. h4
See example games.
A2.2.2 BronsteinLarsen line, 5...gxf6
This is the more dynamic line; Black hopes to make good use of the halfopen files.
6. Nf3 Bg4
[6... Bf5
is the normallooking move, but it isn't very good here e.g.
7. Bd3 Bg6 8. OO Qc7 9. c4 Nd7 10. d5 OOO 11. Be3 e5 12. Be2 Kb8

A2.3 Classical Variation with 4...Bf5
Now play:
5. Ng3 Bg6 6. h4 h6 7. Nh3
This is the most exciting line. The main line goes something like:
7. Nf3 Nd7 8. h5 Bh7 9. Bd3 Bxd3 10. Qxd3 Qc7 11. Bd2 e6 12. OOO Ngf6 13. Qe2 OOO 14. Ne5
...when White has a small advantage which is difficult to make any use of.

Now we see the point of the Nf4 move:

White has good chances for attack, although if the attack fails, the missing piece will lose the game.

Well, you won't get the Alekhin line in every game. The French starts:
1. e4 e6
Now play the natural sequence
2. d4 d5 3. Nc3
Black now has an important choice: safe or brave?
A3.1. Rubinstein Variation 3...dxe4 4. Nxe4
This is a solid line but Black lacks counterplay.
A3.1.1 Rubinstein Variation with 4...Nf6
1. e4 e6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6
White can get an advantage through straightforward moves:

variation recently had some recommendations with the idea of getting a line for the Bishop with Bc6, but White shouldn't be short of play:5. Nf3 Bc6 6. Bd3
6...Nf6
(6...Nd7 may be better)
7. Nxf6+ gxf6 8. Qe2
+/ Levy.
A3.1.3 Rubinstein Variation with 4...Nd7
1. e4 e6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nd7
The main line, which, however, promises Black little. There have been many lines explored here but as an example you could play over:
5. Nf3 Nf6 6. Nxf6+ Nxf6 7. Ne5
White has a small advantage with easy development. Tarrasch showed us several times how to play these positions: see EG.
A3.2. Guimard Variation 3. ... Nc6
In this line, Black cannot play the natural counterattck ...c5, and the other break with ...f6 is riskier. Now
4. e5
4...Nge7 5. Nce2 Nf5 6. Nf3 b6 7. Nf4+/
leaves Black without scope, so Black should prefer
4...f6
when, after
5. exf6 Nxf6 6. Nf6 Bd6 7. Bg5 OO 8. Bd3 Bd7 9. Qd2 Qe8 10. OOO Qh5 11.Rde1
White has pressure along the efile and is in any event more actively placed.
A3. 3. Classical Variation, 3...Nf6
This is met by:
4. Bg5
The natural reply here is the balancing ...Be7 but Black has two alternatives: ...Bb4 and ...dxe4.
A3.3.1. The Burn Variation, 4... dxe4
This has obvious links with the Rubinstein line.
5. Nxe4 Be7 6. Bxf6
And Black has tried both recaptures:
6...Bxf6 (Variation 1)
Black has the two bishops and is solid; White can claim only a small advantage.
7. Nf3 Nd7 8. Qd2 OO 9.OOO b6 10. d5 Ne5 11. Qf4 Ng6 12. Nxf6+ Qxf6 13. Qxf6 gxf6
...when White hopes that the greater harmony of the pawns will give the advantage.
6... gxf6 (Variation 2)
A more risky and more dynamic try.
After 7. Nf3 Black hopes the two bishops and open d and gfiles will give active play. White should develop properly and aim for d5, breaking open the position.
A3.3.2. The MacCutcheon Variation, 4... Bb4
This line still offers Black some prospects of a counterattacking game, but is not as good as the Winawer.
5. e5 h6 6. Bd2 Bxc3 7. bxc3 Ne4 8. Qg4 g6 9. Bd3 Nxd2 10. Kxd2 c5 11. Qf4 Nc6 12. Nf3
White has the idea of dxc5 and Nd4, with advantage.
A3.3.3. The Classical Variation 4... Be7 (and Alekhin Chatard attack with 6. h4)
Again White's move is easy to remember:
5. e5 Nfd7
6. h4
This is, at last, the AlekhinChatard Attack. White offers a pawn for chances of attack. Just how good this line can be is shown by the following miniature:
Zuber,M  Halmkin,P (Exeter Vs Teignmouth, 1995)
1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Be7 5. e5 Nfd7 6. h4 Bxg5 7. hxg5 Qxg5 8. Nh3 Qe7 9. Qg4 g6 10. Bd3 b6 11. Nf4 Ba6 12. Bxg6 fxg6 13. Nxe6 Nf8 14. Nxd5 Nxe6 15. Nxe7 10
Good, isn't it?
Black has various ways of declining the gambit, but none are very promising (analysis from BCO2 and elsewhere):

A3.4. The Winawer variation, 3... Bb4 and Alekhin Gambit 4. Nge2
Black takes a risky decision  to attack White's Knight but with the important darksquared bishop. White has the main try 4. e5 but also some ways of avoiding these critical lines, including the gambit lines 4. Nge2 and 4. a3, and the Winawer Exchange 4. exd5.
4. Nge2
Another Alekhin Gambit
Black is advised not to hang on to the pawn, but to concentrate on good development instead.
