After landing Runway 13 instructed to Taxi K; Runway 22; P3 to gate. Turned on to Runway 22 and noticed blue marker to our right.  Asked ATC about them and was informed that is the taxiway for Runway 22. Transitioned so as to be between those. There are no NOTAMs regarding a designated taxi lane on Runway 22.  Only NOTAM listed is Runway 22 closed taxi only. I feel that the NOTAMs need to be corrected to indicate Runway 22 has an established taxilane and ATC not use the term taxi Runway 22 to P3.  Instead join taxilane on Runway 22 to P3.  Apparently there have been numerous people doing the same thing.  Markers are not lighted and very short with only reflective tape.
Instructed to taxi to the gate after clearing [Runway] 13 via K [Runway] 22 P3. After entering Runway 22 we noticed unlit blue markers on the runway and transitioned between those. NOTAM doesn't mention that runway has been modified to a temporary taxiway that is on part of the runway with unlit nonstandard markings. Provide more info in the NOTAM and taxi instructions that highlight the change. The taxi instructions should not reference Runway 22 but call name it a temporary taxiway which is what they have constructed over Runway 22.
Pilots reported confusing taxiing instructions at AMA airport and lack of a NOTAM to clarify the issue.
