Plasma energy is ions and electrons, matter.
Do you believe a Spirit body is made up of matter?
Matter is physical.
I believe a spirit body is made up of the other dimensional qualities of reality, so if by matter you mean the matter that conventional physics teaches is matter then no, but nobody really knows what the other dimensions are really made of exactly (for that 'matter' [no pun intended] we do not really know what conventional matter is made of other than labelling it a form of energy) and if they can be classes as also being matter or matter 'like'. Only God knows the answer to these questions.
But if you are going to refer to Jesus' resurrected body and when Thomas touched Him or when He broke bread and ate the broiled fish that same day (thus breaking His Esther fast) then that again is something different to a pure Spirit body.
