  Berry curvature acts analogous to a magnetic field in the momentum-space, and
it modifies the flow of charge carriers and entropy. This induces several
intriguing magnetoelectric and magnetothermal transport phenomena in Weyl
semimetals. %, including the planar Hall and planar Nernst effect. Here, we
explore the impact of the Berry curvature and orbital magnetization on the
thermopower in tilted type-I and type-II Weyl semimetals, using semiclassical
Boltzmann transport formalism. We analytically calculate the full
magnetoconductivity matrix and use it to obtain the thermopower matrix for
different orientations of the magnetic field $(B)$, with respect to the tilt
axis. We find that that the tilt of the Weyl nodes induces linear magnetic
field terms in the conductivity matrix, as well as in the thermopower matrix.
The linear-$B$ term appears in the Seebeck coefficients, when the $B$-field is
applied along the tilt axis. Applying the magnetic field in a plane
perpendicular to the tilt axis results in a quadratic-$B$ planar Nernst effect,
linear-$B$ out-of-plane Nernst effect and quadratic-$B$ correction in the
Seebeck coefficient.
