I have no onion powder and the recipe calls for it
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
What are you making? A small amount of fresh onion or scallions can provide the same flavor. Onion salt if you have it, then adjust the salt in the recipe.

Maybe too late for your urgent cooking, but if not:
1) other alternatives...a little bit of garlic or leek
2) if only a small amount of onion powder required, you may make the dish without it
3) if you want a sharp or umami flavor to replace it, consider mushroom, mustard, hot pepper, horseradish, soy sauce, miso...
