Preheat oven to 450°F.
Set a wire rack on a baking sheet; coat with cooking spray.
Place breadcrumbs, lemon pepper, garlic powder, paprika, and salt into a shallow bowl and mix thoroughly (a pie plate would work great!). Place flour in a second shallow dish and egg whites in a third.
Dredge each strip of fish in the flour and then dip in the egg; roll in the breadcrumb mixture, coating on all sides. Place on the prepared rack and spray lightly with cooking spray.
Bake 10-15 minutes until fish is cooked through and the breading is golden brown and crisp.
Meanwhile, peel and dice carrots.
Steam carrots and peas (either over the stove or using a steamer) and serve alongside fish with orange wedges on the side.
