You may be a deist. It depends on exactly what you mean by belief in God. If you believe in God's existence, but you do not believe in a "personal God," you could be a deist.
You may be a "None" This is the term used for people who do not self-identify with any particular religion. Close to one-fourth of Americans are Nones, and their ranks are growing. Some of the Nones are atheists/agnostics, but others believe in God, but are not affiliated with any particular religion. About two-thirds of the Nones believe in God.
You might be "spiritual but not religious." A little over a fourth of Americans describe themselves with this term.
You might even be a pantheist. Do you believe that "God is Nature"? If so, you might be a pantheist. Pantheism is the belief that God is not a separate entity, but rather is found in the entire natural universe.
You could even be an emerging-atheist (to coin a phrase). Giving up religion is the first step to atheism. I hope you will continue on this path.
