  We combine in-situ electrical transport and Seebeck coefficient measurements
with the ionic liquid gating technique to investigate superconductivity and the
normal state of FeySe1-xTex (FST) films. We find that the pristine FST films
feature a non-Fermi liquid temperature dependence of the Seebeck coefficient,
i.e., S/T ~ AS lnT, and AS is strongly correlated with the superconducting
transition temperature (Tc). Ionic liquid gating significantly raises Tc of FST
films, for which the Seebeck coefficient displays a novel scaling behavior and
retains the logarithmic temperature dependence. Moreover, a quantitative
relationship between the slope of T-linear resistivity (A\r{ho}) and Tc for
gated films is observed, i.e., (A\r{ho})1/2 ~ Tc, consistent with previous
reports on cuprates and FeSe. The scaling behaviors of AS and A\r{ho} point to
a spin-fluctuation-associated transport mechanism in gated FeySe1-xTex
superconductors.
