Preheat your oven to 425°F (220°C) and set a wire cooling rack over a large rimmed baking sheet lined with parchment paper.
Pat the chicken wings thoroughly dry with paper towels to remove all surface moisture, which is essential for achieving a crispy skin.
In a large mixing bowl, whisk together the baking powder, garlic powder, ginger powder, sea salt, and black pepper.
Add the wings to the bowl and toss vigorously until every piece is evenly coated in the dry seasoning mixture.
Arrange the wings on the wire rack in a single layer, ensuring they are not touching to allow for optimal heat circulation.
Bake for 35 to 40 minutes, flipping the wings halfway through the cooking time, until the skin is golden brown and very crispy.
While the wings bake, combine the tamari, rice vinegar, sesame oil, and honey in a small saucepan over medium-low heat, simmering for 3 minutes until slightly thickened.
Transfer the hot wings to a clean bowl, pour the warm soy-garlic glaze over them, and toss until every wing is glistening.
Plate the wings and garnish with toasted sesame seeds and thinly sliced green onions for a fresh finish.
