Perished outside Luxor, finally preserved as mummy? (5)
I believe the answer is:
dried
'preserved as mummy?' is the definition.
(as in mummifying a body)
'perished outside luxor finally' is the wordplay.
'perished' becomes 'died' ('die' can be a synonym of 'perish').
'outside' means one lot of letters goes inside another.
'finally' suggests the final letters.
The last letter of 'luxor' is 'r'.
'died' placed around 'r' is 'DRIED'.
(Other definitions for dried that I've seen before include "Like clean dishes" , "Forgot words (on stage)" , "Parched" , "With moisture removed" , "dehydrated" .)
