In a medium bowl, mash the chickpeas lightly with a fork or potato masher until they’re slightly broken but still have some texture.
Add olive oil, dried oregano, garlic powder, onion powder, smoked paprika, salt, and pepper to the mashed chickpeas. Mix until the chickpeas are well coated with the spices.
Heat a non-stick skillet over medium heat. Add the chickpea mixture and cook for about 5-7 minutes, stirring occasionally, until the chickpeas are heated through and slightly crispy on the outside.
Warm the whole wheat pita bread in a dry pan for about 1 minute on each side until soft and pliable, or wrap them in foil and place in a preheated oven at 350°F (175°C) for 5 minutes.
Spread a generous amount of vegan tzatziki sauce on each pita. Top with the chickpea mixture, diced cucumber, diced tomato, and sliced red onion.
Garnish with freshly chopped parsley or mint leaves for added flavor and freshness. Fold the pita over to create a wrap and serve immediately.
Notes
Serve the gyros wrapped in parchment paper for a rustic touch, alongside a small bowl of extra tzatziki sauce for dipping.
