Adam Wathan has created a Laravel package, Eloquent OAuth:
Eloquent OAuth is a package for Laravel designed to make authentication against various OAuth providers ridiculously brain-dead simple. Specify your app keys/secrets in a config file, run a migration and from then on it’s just two method calls and you have OAuth integration.
This package differs from Socialite, the Laravel OAuth package, in that it ties directly into creating users and logging them in. Also, Eloquent OAuth supports a few different providers, including Facebook, GitHub, Google, LinkedIn and Instagram.
Update: Adam created a short video showing off the package:
