After further cooling, most of the electrons became bound to nuclei, and all the matter became plasma, like most of the matter in the present universe still is (because most of the matter is inside the stars).
When electrons bind to nuclei, a plasma turns into a neutral gas, this happened in the recombination phase. The neutral gas then collapsed into stars which turned the gas making up the stars back into plasma. Also the energetic photons emitted by stars started turning the remaining gas back into a plasma which is called the reionization phase.
