Place the tofu on a clean dish towel and cover, pressing lightly to remove some of the moisture. Slice into ½-inch cubes. If it still feels very wet, put the cubes in the dish towel and lightly press to dry it again. It doesn’t need to be pressed or bone dry - the slight moisture will help the spices stick.
In a medium-sized bowl, mix the flax meal, starch, and spices in a bowl until thoroughly combined.
Add the tofu pieces to the bowl and toss well until all pieces are thoroughly coated.
Line a baking sheet with parchment paper, lay out the tofu pieces so they are not crowded, and there is space around each. Bake for 15 minutes.
NOTE: Conversely you can use 1½ tsp. of curry powder in place of the turmeric, cumin, coriander, and garlic powder.
