As Vikings you attack. In any land you take (even if they are hiding in the castle) you get the value of all religious buildings destroyed by the raid. Further raiding in that province involves taking the castle/town and destroying individual buildings. As Viking you get full value for them, other factions get 1/2 value.

In MTW raiding is the same way except everyone gets 1/2 value for destroyed buildings.

Another value in raiding is prisoners. Rebels are worth some small amount, and other faction soldiers (especially generals) are worth much more. Light Cavalry is best for chasing/capturing routers.
