Preheat oven to 400 degrees F. Spray a large baking sheet with cooking spray.
In a wide shallow dish, add the eggs, garlic powder, salt, and pepper. Whisk until well combined. In a second wide shallow dish, add the panko breadcrumbs and shredded coconut. Stir to combine.
Dip the chicken tenders in the egg mixture, coating both sides. Lift the chicken out of the egg and allow the excess to drip off. Place the egg coated chicken into the coconut mixture. Press the coconut mixture into the chicken ensuring that all sides are completely coated. Place the coconut coated chicken on the prepared baking sheet. Discard the excess egg and coconut mixture. Spray the tops of the chicken tenders with cooking spray.
Bake on the middle oven rack for 12-14 minutes, until the chicken is cooked through and the coating is crisp and golden brown.
