Mix cumin, salt, black pepper, chili powder, garlic powder, onion powder, paprika, and oregano together in a small bowl. Set half of this taco seasoning aside for the recipe, and save the other half for future use.
In a medium or large skillet over medium-high heat, sauté the plant-based meat substitute, stirring occasionally until browned. Reduce the heat to low and stir in the water and taco seasoning you set aside. Continue to sauté, stirring occasionally until bubbly and well blended (3-5 minutes).
Meanwhile, cook the dairy-free egg substitute according to package directions and scramble.
Portion some of the plant-based meat on a tortilla and top with egg, cheese, sour cream, and salsa. Add cilantro and hot sauce (if desired).
