Taco spice ?

You know how when you make tacos and you add the taco spice mix to the meat. It could be Ortega or one of those. Here's the question:

If you were trying to duplicate the spices in the packet from your spice cupboard, what all do you think is in there?

I'm thinking cumin? chili powder? paprika?

On list of ingredients it says "spices" - Big help they are :-)

Thanks for any ideas!
