In a medium bowl, combine soy sauce, brown sugar, orange juice, jalapeno powder, Cajun seasoning, garlic powder, and onion powder.
Mix all the ingredients together until well combined.
Place steaks in a shallow dish or resealable plastic bag.
Pour the marinade over the steaks, ensuring they are evenly coated.
Cover the dish or seal the bag, and refrigerate for at least 4 hours, or overnight for best flavor.
When ready to cook, remove the steaks from the marinade and discard any excess marinade.
Grill the steaks to your desired level of doneness.

Wine Advice:
The bold and spicy flavors of this fusion marinade call for a wine with some sweetness and acidity to balance it out. Try pairing with a slightly chilled Riesling or Gewürztraminer.
