you can cook them like tempura.
get the firm tofu, slice them into serving portion, soak them into beaten egg or you can mix flour and water as your batter...roll them in panko Japanese bread crumbs...deep fry them until it turns golden brown.
arrange the tofu tempura in a platter, drizzle them with tempura or katsu sauce, sprinkle some roasted black and white sesame seeds and top them with cilantro for garnishing.
or you can dip it in tempura sauce, katsu sauce or you can be creative on where to dip them.
