Eltab
Lord of the Hidden Layer
Orcs could revere the Mordenkainen Correlon (never by that name!) as the source of the formless ever-moving magical power which their wizards learn to tap and form and control.
Silvanus (nature red in tooth and claw) would adapt easily to many worlds' Orcs.
Yondalla might be seen as a patron goddess of children and places made safe for those not yet strong enough to do that task themselves. (And her dark side, Dalla Yon, empowers those who seek new homes for the tribe to settle into and make them safe places to raise children.)
Even if Orcs have Sunlight Sensitivity, they recognize the need for light to make plants grow so animals can eat them and become bountiful feasts for orcs, so a Sun god can fit in a pantheon. Maybe as a remote figure who just sticks to his own job and doesn't interfere in other beings' doings.
