Incorporate me on returning corpse (6)
I believe the answer is:
embody
'incorporate' is the definition.
(both can mean to give physical form)
'me on returning corpse' is the wordplay.
'on returning' is a reversal indicator.
'corpse' becomes 'body' (I've seen this before).
'me' backwards is 'em'.
'em'+'body'='EMBODY'
(Other definitions for embody that I've seen before include "Express, say ideas, in visible form" , "Epitomise" , "Incorporate or express in visible form" , "concretise" , "Express concretely - personify" .)
