Start by removing the tofu from its container and lightly dry it with a paper towel. You want the tofu to be moist, but not soaking wet. Set aside.
Then, add the cornstarch, nutritional yeast, salt, pepper, and garlic powder to a mixing bowl and whisk togehter.
Cut the tofu into 12 evenly sized rectangular slices and dunk each slice individually into the bowl of batter. Mix until coated. If you have excess batter after dunking the tofu once, go ahead and dunk them in the batter again.
Heat the oil in a non-stick pan. Once it has warmed for about 1 minute, add in the dry coated tofu slices.
Pan-fry the tofu slices for about 5 minutes on each side until crispy and browned. Then, carefully rotate each slice with a spatula to cook on the next side. Do this 4 times to get all of the sides browned and crispy.
Remove the tofu slices from the pan and serve immediately. Enjoy!
