Prepare tofu by pressing and draining the extra-firm tofu to eliminate excess moisture. Cut tofu into bite-sized cubes.

Coat the tofu by mixing cornstarch, garlic powder, and a pinch of salt in a bowl. Toss tofu cubes until evenly coated.

Cook the tofu by frying it in a non-stick pan with heated oil for 3-5 minutes on each side until golden-brown or bake at 400°F (200°C) for 25 minutes.

Make the sauce by combining fresh orange juice, sugar, and soy sauce in a saucepan. Heat over medium-low until mixture thickens, about 5-7 minutes.

Combine by transferring the cooked tofu to a bowl and pouring the orange sauce over it. Toss gently to coat the tofu in sauce.
