Pre-heat oven to 350 F (177 C).
In a good blender, add tofu, lemon juice, white wine vinegar, onion powder, garlic powder, salt, nutritional yeast, mustard seed. Blend well until smooth.
Use a cheese cloth to drain the excess juice from the crushed pineapple; the better you drain this, the less mushy your enchiladas will be.
In a bowl, mix blended mixture with 1/2 cup of shredded cheese and your drained crushed pineapple.
In a 9 x 13” casserole dish, spray with Olive Oil (or something similar) so nothing sticks.
Pour 1/2 of the can of enchilada sauce into the dish and spread evenly.
Fill each tortilla with ~1/6 of the filling mixture and roll them into enchiladas. Place in casserole dish.
Once all six enchiladas are done, pour the remaining enchilada sauce over them.
Sprinkle remaining shredded cheese on top.
Bake for 23 - 27 minutes. Covering the casserole dish will help the vegan cheese melt better.
