Prepare Marinade: In a mixing bowl, whisk together the vegan yogurt, Dijon mustard, agave, lemon juice and zest, olive oil, soy sauce, minced garlic, nutritional yeast, smoked paprika, onion powder, dried oregano, and dried thyme until the mixture is smooth.

Prepare Tofu: Pat dry the super firm tofu with a clean kitchen towel and cut into bite-sized chunks.

Marinate Tofu: Toss the tofu pieces in the prepared marinade, ensuring each piece is well-coated. Let it marinate for at least 15 minutes.

Cooking: Heat a non-stick skillet over medium heat. Thread marinated tofu onto skewers and cook for 3–4 minutes on each side until golden brown.

Finish Tofu: Toss the cooked tofu with the reserved marinade for an extra kick of flavor.

Serve: Warm the pita bread, place crispy tofu on top, and drizzle with homemade Vegan Tzatziki.
