First, don't start the engine if there's no oil! Oops .. too late! You might be okay but I'm thinking if there really wasn't any oil ... you'll have to replace something. Not sure what, rings maybe, but something.

What color is the smoke coming out of the tail pipe? Is it blue, white, black? I assume its blue since you said oil is in the tailpipe. I'm suspecting the oil separator. I guess you have oil inside your engine now and need to have it cleaned out. Might try a search as I think others have had to do that before.

Did you check what kind of condition your separator, hoses, valve cover gaskets, etc are in now? I assume you had it replaced before and not changing it now. If you just replaced it now - what kind of condition was the old separator?

I'm sorry I don't have more useful ideas but hopefully people with more knowledge/experience will post soon.

Hmm, that means you're getting anti-freeze in the engine. I'm not sure where to go from here. Head gasket could be bad, cracked block. However, you have to figure out the root cause of all this. What about the oil separator. Did you just change it now or before?

Did you check for leaks (oil/anti-freeze) on the engine itself or on the floor/ground?

Again, someone else will probably have some better ideas. If you're not handy with cars/engines then you probably will want to take it to a mechanic anyways.
