Well, I have a personal "path" that I follow centered around kind of like a table-ish structure. Deities are from the Egyptian pantheon, though I have yet to find a non-local deity of water in it (If any of you guys could help with that it'd be wonderful).
Now the table-ish structure. The basic concept is that five ideals, or pillars/legs supporting the table or top, which consist of wisdom, fire, earth, water, and air, supporting a table/top made up of a triple-goddess of wisdom thing, primarily the one the Sekhmet and Hathor fall into (I can't think of the third one off the top of my head, so if you guys don't know the third one, I'll post it when I find it again). Because Sekhmet is related to both fire and willpower-gone-rampant/lack-of-willpower-ish, her position in the structure changes depending on the ritual purpose she is being called on to assist with. Finally, atop the entire thing, sit two chairs, one for the God (Osiris), and one for the Goddess (Isis).
Aside from the major deities of the path, the other major emphasis is on natural magicks.
Finally, when doing a ritual in the outdoors (one way natural magicks get into my normal pattern of rituals), as each deity/piece of the structure is invoked, the physical representation is placed on the altair, thus constructing the entire table-thing. Because the quarters are part of the structure, there is no "calling the quarters", simply an "invoking of the columns."
The rest is much more complex, and there isn't enough room here for me to fully describe it without trying to pull my hair out.
