Mix all chicken marinade ingredients in a large bowl. Marinate the chicken for at least 30 minutes, or preferably leave it to marinate overnight in the fridge.
Heat a griddle pan and add the chicken strips. Cook each side for 2-3 minutes until completely cooked. Set aside. Wipe the pan clean, add a splash of olive oil and add the peppers and onions. Add the vegetable powder and soy sauce and cook until softened.
In a bowl, mix all ingredients for the guacamole.
To assemble the tortillas, spread some yogurt and guacamole, add the chicken strips and top with the cheese, corn and chopped tomatoes. Fold both sides to create a wrap and enjoy!
