It's difficult to say, without seeing where under the hood it's coming from. You could have a bad exhaust manifold gasket, leaking exhaust. You could have valve cover gaskets leaking or seeping oil, which would drain onto the hot exhaust manifold, and burn off... If you can provide more information on where the smoke is coming from, there may be a better answer.
