Each nonland permanent you control becomes a copy of target non-Aura permanent.
"Quiet is beyond the night
Changeling, take my form tonight
Prove my life was not for naught
Changeling, see I'm not forgot."

The permanents copy exactly what was printed on the original permanent and nothing else (unless that permanent is copying something else; see below). They don't copy whether that permanent is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

Because the permanents aren't entering the battlefield when they become copies of the target permanent, any "When this permanent enters" or "This permanent enters with" abilities of the copied permanent won't apply.

If the copied permanent is copying something else, then the permanents become copies of whatever that permanent copied.
