You can take some kind of class at a local community college, university,or arts and crafts store. Start attending some casual community activities, maybe look for a community organization like the Rotary Club, Kwianis, Lions, Knights of columbus group. Not sure if your into it but my experience is just do to a church service of your choosing. Occasionally I decide I want to formally touch base with God and it doesn't matter where I end up going... SOMEONE always approaches and engages with me. It maybe a church elder or the church busy body but...this person is your doorway to the group. Just be nice, indicate an interest and other relationships will follow. This just isn't true of church people, I think it is true of most groups. When in a group you need to look around and see who seems to play the roll of initial greeter/new member recuiter.
