As a little spin on Hjorimir's suggestion, consider the show "Joan of Arcadia" and (as you have) the Crow movies.
In both cases, the main characters receive info from divine sources- in the former, its direct contact, which you already said you don't want. Still, it was handled excellently, so it might give you some ideas for down the road. God appeared to Joan by talking through the mouths of regular people around her.
In the Crow movies, though, the main character had a divine familiar of sorts, that gave him hints and clues "Lassie style." The crow in question would circle around or land on things of import to the main character, hinting, guiding, but never talking.
Similarly, a creature or creatures (a pair of creatures, a swarm, whatever) connected to the lost god in some way could hint at things important to the god. It doesn't even have to be the same creature. Perhaps its a species that is unusual to the area, so it stands out. Perhaps it gets noticed because of unusual markings- albinism, the god's holy symbol in its hide patterns. If birds are connected to the deity, perhaps the marker is that the bird in question sings a song that used to be used in the god's services. Bugs could swarm in unusual ways...especially if the bugs aren't known for swarming outside of mating season...like butterflies.
