You have to directly apply the ICE table method to your case.

What is your HA? A-?

Basically it is about stoichiometry - from the dissociation reaction you can easily see that for each mole/molecule of A- (H+) produced, one mole/molecule of HA is consumed. You just have to express concentrations of all three substances involved (HA, H+, A-) in terms of one unknown - best approach is to use H+ as the unknown, as you are asked about pH.
