I'm drawing from Precepts of The Brahman Net Sutra, Upsasaka Precepts Sutra, and Avatamsaka (Flower Garland) Sutra.
The BNS recommends this worldly Bodhisattvas (monks and laity)
Hosting vegetarian feasts for monks, lay Bodhisattvas, get mention in the BNS and Ullambana Sutra.
As for celestial Bodhisattvas, we don't get a lot of clues. The 7th to 10th Bhumis (grounds) describes what celestial Bodhisattvas do-- I don't have a good summary for that though.
And finally, there are the vows. Amitabha helps people reach enlightenment by guaranteeing rebirth in a pure land, which depending on who you are reading, is describe as an especially good place for practicing Buddhism, as compared to our own universe, where the most recent Buddha has passed on and there isn't another one available to teach.
Samantabhadra's vows has some more clues, such as encouraging Buddhas to come & stay in our universe-- since it is easier to become enlightened when there is a Buddha available, and transferring merit
