In a large mixing bowl, whisk the yogurt and spices together.
Chop the chicken pieces into small pieces.
Add the chicken into the bowl and cover each one generously with the yogurt-spice mixture.
Place in the fridge for an hour to allow it to marinate.
Preheat the air fryer for 5 minutes at 375°F (190°C).
Place the chicken on air fryer basket for 20 minutes, flipping the chicken every 5 minutes or so. (Don't overcrowd the basket, make in batches as necessary).
Open the air fryer to see if they are crispy enough for you, and heat them for a couple more minutes if you wish.
Serve while warm.
Notes
*If using frozen chicken, let it defrost naturally for at least 1 hour beforehand.
