You would just replace the liquid in a recipe with Beer. We had a pizza place when I was growing up that used beer in the recipe of their dough, of course, they weren't giving it out and only family worked there.
From my thoughts, I'd think you'd do well to go with something malt forward and not too hoppy. A nice roasted malt flavor would go great in a pizza dough, imo. I'm not sure how the hops would hold up though going through the heating of the crust, so for the first batch I'd stay away from heavily hopped beers. That is only my opinion though, never made any myself.
