Which dead god temples do you keep?

I mean in the prologue.

For me, the only one that's a must is Issaries. Two extra trade routes is a huge plus.

Ernalda helps with certain events, some of which help with food, and can also help you defeat Nontraya the Taker. Still not sure if it's worth paying so much upkeep though.

Orlanth is similar but doesn't influence food, so it seems less useful.

Lhankor Mhy I kept once but it never seemed to influence events at all. Though I guess it may have some passive bonus.

I keep a shrine to Issaries and occasionally Ernalda (hers is especially good for the food events)

Lhankor mhy helped me calm the ancestory ghosts down when they show up

And Orlanth kinda seems a bit useless? Haven't gotten many uses out of that one so I never upkeep it anymore

Orlanth does help with some events, such as when your Orlanth worshippers start choking and fall ill. You get the option to call upon him to cure them, which is easier if you have a temple.
But yeah, the question is whether temples to him and Lhankor Mhy are worth the annual sacrifice. I'm inclined to say no.

Temples to Ernalda and Issaries usually, sometimes a shrine to Orlanth as well but never anything more.
