Put the chicken wings in a large self-sealing plastic bag. Mix the soy sauce, honey, vegetable oil, and dry mustard in a bowl, then pour it into the bag. Close the bag securely and shake until all the chicken is well coated. Refrigerate the chicken wings, in the bag with the marinade, for at least 2 hours.
Preheat the oven to 375 degrees F. Line a baking sheet with aluminum foil, and place a rack on top of the foil. Remove the chicken wings from the bag and place them in one layer on the rack. Bake for 30 minutes, or until the chicken wings are crisp and golden.
