Cut the tofu in cubes and place in a bowl. Using a fork, mash the tofu until it turns into crumbles.
Heat a large skillet to medium heat and add a tablespoon or 2 of oil. When the oil is hot, add the tofu to the pan and cook while stirring with a spoon occasionally until the excess moisture has evaporated off the tofu.
At this point the tofu should move more freely around the pan and seem less sticky.
In a small bowl, dissolve the tomato paste in the water and add the chili powder, sea salt, cumin, paprika, onion powder and nutritional yeast then mix well.
Pour the spice mixture over the tofu and reduce the heat to low. Allow the tofu to simmer in the sauce for about 10 mins, or until the tofu has absorbed most of the water......
