After a month away from the game I'm coming back and trying to learn terran. I'm competent with zerg and toss, was upper platinum before my long hiatus (months of custom games then a month of nothing at all).

What kind of builds should I be doing against each race? I've been practicing a bit of 2 rax/fast expand (with a little bunker rush) against zerg and 3 rax against toss with moderate success. My main problem so far is not getting enough production buildings, or the right ones, at 2 and 3 bases.
