  We study the thermoelectric properties of monolayers of MoS$_{2}$ and other
group-VI dichalcogenides under circularly polarized off-resonant light.
Analytical expressions are derived for the Berry phase mediated magnetic
moment, orbital magnetization, as well as thermal and Nernst conductivities.
Tuning of the band gap by {\it off-resonant} light enhances the spin splitting
in both the valence and conduction bands and, thus, leads to a dramatic
improvement of the spin and valley thermoelectric properties.
