Lord Of Fire: The Silver Mage Series: Book 1 — P.L. Nunn

The Silver Mage. Dante Epherian was the greatest wizard the world had ever known, and the most dangerous, until he'd died defeating an evil that had threatened to extinguish humanity. And the world rested easier, two greats threats nullified in one fell blow. All but the girl who'd loved him despite of himself. But you can't keep a good Wizard - - or a notoriously wicked one - - down. Only the world is a different one than the one he left, a world with a new religion and a new prophet who is more than he seems. The Silver Mage finds himself on the run, with his former brethren none the wiser and with ancient wards binding his awesome power, he has to rely on more mundane methods of finding freedom and dealing vengeance on the man that shackled him. Book 2 out soon.
