I looked over the net for sample response files for profile creation in WAS 8.5, but I found none. Well, I didn't expect much of a revolution in comparison to V7 or V8, but still, better be safe than sorry :)
So I ended up converting possible listed manageprofiles flags into response file entries, in a traditional manner. The result was as follows and you can safely use it as a starting point for your profile management automation.
#profile name and capabilities
#location and names
#standard WAS keystore/truststore password
