Ritual in buddhism (preferably theravada) for lay people

Perhaps ritual isnt the right word but hopefully I can explain. So I am attracted to orthodox Christianity and its culture but I dont believe any of it. I like its fasting ritual many of its holidays, its worship and etc. and being in the west its easy to find like minded people to make that a part of my life or rather part of my practice. Buddhism by oneself is basically reading suttas and meditation since there is no local sangha but I find I would like to integrate more in my life so I can inundate my existance around buddhism without monasticism. I cant become a monk I have a wife and children. Is there anything like a Buddhist lifestyle beyond the 5 precepts for laypeople to follow to make it more "holy"?
