You do not have to make it into a powder you can just rehydrate the bigger pieces and that will work fine. I will typically just break up clay I am reclaiming into quarter sized pieces and let it rehydrate for like a week. I'll mix it as it is dehydrating, maybe once every couple days. Then when I want to reclaim I will just pour off the extra water and put it on plaster.
You do not have to wedge it all at the same time. You could do whatever mixing method you want, then wedge small portions for throwing. I think the air bubbles are coming from the folding.
