Cut the cauliflower into bite-sized florets. Dip the florets into the batter, so they're completely coated. Then roll them in the panko bread crumbs. Line a baking sheet with parchment paper and lay the cauliflower florets on the baking sheet. Don't put them on top of each other. Bake for 25 minutes. In the meantime, make the general tso sauce.
