Is it okay to teach my future kids my personal religion?

Ok, so religion is obviously a touchy subject for everyone, but my honest opinion is to teach them your religion and let them get to know it, but also don't hold them back if they want to discover others. Because in the end, it it their decision.

I think that you should raise them how you fit but if they resist to accept the religion they grew up believing, you shouldn't disown them. Simple as that. They're going to be capable of choosing their beliefs sooner or later and as a parent you must support them.

You sound like you want to teach them mainly to find their own religious beliefs through an exploration of themselves. That's excellent. You can tell them all about the things you've come to believe in, and you can teach them about other religions, if you want to. The important thing is that if they have differing beliefs, you are open and receptive and accepting of that.

I was raised in an atheist household and I really appreciated it, but I feel like I missed out on a lot of the strong community religion can bring, but on the other hand I know quite a few people who were raised in Christian/religious households and resented their parents quite a lot for it.
My suggestion is while you can teach your children about your own personal beliefs (because that sort of community support can be so good for childre) you shouldn't force the religion on your children. Try and educate them on as many belief systems as possible. Make sure they understand that your belief system isn't the only one, and it may not be right. Let them know that they can pick and choose from religions to develop their own beliefs. Teach them that they don't have to agree with everything or anything you say. Let them educate themselves because that's the most important thing. Just try to keep it a very open environment where they can feel free to ask questions without judgement, even if it contradicts with your own beliefs. I think that's the best way to go about it, to be honest. That's how I was raised (besides the whole religious part) and while I chose not to adopt any religion, I really appreciate my parents for giving me that sort of freedom to be who I wanted to be.
