Combine the vegan mayonnaise, soy or rice milk, vegan Worcestershire sauce, 2 tsp lime juice, 1/2 tsp salt, and cayenne pepper. Fold in the avocado and cilantro, then chill.
In a skillet, heat the vegetable oil and sauté the seitan until lightly browned. Add the hot sauce, maple syrup, 1/4 cup lime juice, and 1/2 tsp salt and simmer 5 minutes. Remove from the heat and stir in the fresh oregano.
Assemble the wraps by placing a little seitan with sauce in each lettuce leaf. Add the cucumber, carrots, celery, and sprouts, as desired, and drizzle with the creamy avocado sauce.
Servings: 8 to 10 wraps
