Preheat oven to 400°F.
Take tofu out of package and drain water. Cut tofu into ¼-½”-thick pieces.
Mix 2 Tbsp. cornstarch, garlic powder, and ginger powder. Lightly coat the tofu; this is what is going to make it crispy. Lay coated tofu out on a sprayed baking pan. Lightly spray tops of tofu with cooking spray. Bake for a total of 45 minutes. Flip tofu halfway through the baking.
After tofu bakes, add soy sauce, hoisin sauce, sesame oil, brown sugar, fresh ginger, and fresh garlic to a saucepan. Mix to combine and heat over low heat. Add ¼ tsp. of cornstarch to 1 Tbsp. of cold water to dissolve. Once dissolved, stir into sauce and bring to a boil. Remove from heat. Add the crispy tofu to the sauce and cover with toasted sesame seeds.
Serve over rice, on a salad, or in a wrap.
