I'd say pretty much regardless 95% of the time I get up blocking. I don't like 6D or Daifunka as a staple of any game plan against a character that can do so much damage.
Really, she should put you in pressure no matter what, but if you're playing someone who is truly insistent on not doing that, you can do one of a number of things.
Short: Wakeup, check for attacks, if none, 5A to pressure. Nu is now in a horrible spot, lol. Run trains on her with Bang's legendary pressure.
Mid: Check for swords or poking C's, if none, you can try to poke with 5B or 2B, dependant on range, or you can Tiger Knee Dnails. TK Dnails at mid is nearly a sure fire pressure string, so if you really need the hit it's a good call.
Long: Patience. I'd say probably back jump forward jump forward dash, block. If she hits you, you're going to end up mid rangish or long rangish, but you'll only end up long again if she backs up to the corner, meaning you've made progress. As soon as I touch the ground I'd probably dash forward and reaction anything she throws with more blocks, then predict her trying to get past me. Really though, long sucks. Just try to wait for a mistake, and get in on it. Barrier if you won't lose ground, so you can conserve your shield; your burst is next to worthless in this matchup anyway.
Oh, and I can't stress this enough, if she's ever close to you and you're driving, tech a grab. For those that don't know, even through a throw counter you can tech a grab if you auto-tech it previous to it hitting. This is only true in CT, so make use of it while you can.. it helps Bang more than anyone.
