Preheat oven to 350º. Line a baking sheet with parchment paper.
To make the tofu crumbles - in a medium bowl mix the vegan Worcestershire sauce, water, chili powder, garlic powder, onion powder, & smoked paprika. Then crumble the tofu into the bowl and mix with your hands to coat well.
Spread the tofu crumbles on the baking sheet in one layer. Bake for 35-40 minutes, turning halfway through, until lightly browned.
Towards the last 5-10 minutes that the tofu are cooking, heat a large sauce pan over medium heat. Saute the onions, bell peppers, & garlic with 1-2 tablespoons of broth or water for 3-4 minutes or until translucent. Add more broth or water as needed. Add tomato sauce, Worcestershire sauce, chili powder, cumin and mix until combined.
Add the baked tofu crumbles and stir, bring to a boil and then lower heat and simmer for about 5 minutes or tofu/sauce is thick.
