Preheat oven to 400°F and line a large baking sheet with parchment paper, then spray with cooking spray.
Set up three shallow bowls: one with flour mixed with salt, garlic powder, and pepper; one with beaten eggs; and one with panko breadcrumbs mixed with shredded coconut.
Dip each chicken strip first in flour, shaking off excess, then in egg, and finally press into the coconut-panko mixture to coat completely.
Place coated chicken strips on prepared baking sheet, spray tops lightly with cooking spray, and bake for 22-25 minutes, flipping halfway through, until golden brown and chicken reaches 165°F internal temperature.
Let rest for 5 minutes before serving with your favorite dipping sauce.
