Well... it's kind of EVERY religion if you think of "God" as the Universe, if not then there is no "religion" that practices this, because... well... there's a lack of god.
Bhudism isn't far from this, but it isn't considered a religion in the literal definition, and there's lots more to it than just asking the Universe for stuff.
Beyond that it's more of a philosophy/ life practice etc.
I grew up (Catholic actually) in a little hippy town near San Francisco. The Universe was pretty central in all of our upbringings and moral development. As we were raised, however, it's less about asking for stuff and getting quick answers than about being connected to and reliant on everything and being honest, truthful and kind in everything we did. (ie "don't use negative self-talk because that puts those words into the Universe." "Be kind to others and the Universe will be kind to you." "Work hard and the Universe will see that it's important to you." "Be honest about what you need and the Universe will bring those things to you, if you are dishonest and pretend that you are happy when you are not, the Universe can't know you need help." etc.)
Not sure if you're asking because you're looking for a church, or just to know more about something that makes sense to you. Either way, it sounds like you're on a path that feels good to you. Good luck.
