Lord of Light by Roger Zelazny.

The backstory is that Earth sent out colonizing ships to distant planets. The passengers were kept in suspended animation, while the crews were allowed to clone new bodies and transfer their minds.

This particular planet was colonized mostly by Hindus. After developing super powers to help conquer the hostile native fauna, the crew has declared themselves Gods. They use the Hindu pantheon.
