I didn't exactly take into account your style, but in your own interest you should be ready to play different position types. This isn't going to be so closed, but it will definitely be solid, positional, and you will need to be tactically astute in the moves that follow.
One of the best lines is the following.
- d4 Nf6
- c4 c5
- d5 b5
- cxb5 a6
- bxa6 Bxa6
- Nc3 d6
- Nf3 g6
- e4 Bxf1
- Kxf1 Bg7
- g3 0-0
- Kg2 Nbd7
- a4!
there are some move order wrinkles possible during this but you will manage to reach this tabiya 95% of the time. From here you just have a plan to regroup and neutralise the pressure black has on your queenside. knights on b5 and c4 for example are really nice and Qe2 or Qc2 are useful to protect b2, you can also regroup the darksquared bishop to c3. Sometimes you'll move the rook to a2 and then play b3 thought care should be taken. Also developing the hrook somewhere at some point. Subsequent to consolidating you then have good chances to slowly try to make the pawn count. This is vague but you should analyse from here yourself as it's already quite deep. Hope this helps.
EDIT:
Another option which I frequently use is to simply play 3. Nf3 when you can get some closed English/Maroczy bind position type... or if black insists on playing b5 then a6 you can take all of the pawns (including c5) and black is temporarily down two pawns and will be unlikely to recover them or get sufficient compensation.
