Preheat oven to 200 degrees Celcius.
Cut tofu longways into three pieces.
Mix together the soy sauce, lemon juice and ½ of the water.
Marinate the tofu in the sauce for 1 hour.
If using, cut the seaweed to fit and stick to the tofu slices.
Mix the flour, salt, garlic powder, onion powder and nutritional yeast.
Add the rest of the water and mix until there are no lumps.
Dunk the tofu into the batter, making sure it is well coated, then cover with breadcrumbs.
Place on a baking tray lined with baking paper.
Bake for about 20 minutes or until golden brown.
Serve with chips and tomato sauce.
