Prepare the chicken by cutting it into bite-sized pieces.
In a bowl, combine orange juice, zest, cilantro, garlic powder, onion powder, cayenne, salt, and pepper.
Add the chicken pieces to the marinade and let sit for at least 30 minutes.
In a shallow bowl, combine flour and breadcrumbs.
Heat oil in a frying pan over medium heat.
Coat marinated chicken pieces in the flour and breadcrumb mixture.
Carefully add the coated chicken bites to the hot oil.
Fry until golden brown, about 3-4 minutes on each side.
Remove the chicken bites and place them on a paper towel-lined plate.
Serve warm with extra cilantro and orange wedges if desired.
