Suppose i have a wooden ring and a time varying magnetic field is passed through it. Then will there be induced emf.

Sure. The changing magnetic field creates an induced electric field.

The induced EMF would be present even in a vacuum! :)

As I said before, it's the changing magnetic field that induces an electric field. (To understand that better, explore Maxwell's equations.) Perhaps you are thinking of an induced current: that will require a conducting loop. But the electric field is there, conducting loop or not.
