The Mythic Odysseys of Theros lists, for each of the gods, the domains most associated to them. As well as this is listed the suggested classes. Here is an example:
Alignment: Usually lawful, often evil
Suggested Classes: Cleric, monk, rogue, wizard
Suggested Cleric Domains: Death, Grave (described in Xanathar’s Guide to Everything)
Suggested Backgrounds: Hermit, sage, sailor, urchin
Obviously this isn’t an exhaustive list.
However, I haven’t found a similar mapping for the Warlock Pacts or Patrons.
Does any information on this exist in the book (that I’ve missed) or is it available elsewhere?
If not, which gods/monsters/entities make sense for each pact and patron?
