We present an analysis of electron recoils in cryogenic germanium detectors operated during the SuperCDMS Soudan experiment. The data are used to set new constraints on the axioelectric coupling of axion-like particles and the kinetic mixing parameter of dark photons, assuming the respective species constitutes all of the galactic dark matter. This study covers the mass range from 40 eV/ to 500 eV/ for both candidates, excluding previously untested parameter space for masses below ~1 keV/ . For the kinetic mixing of dark photons, values below are reached for particle masses around 100 eV/ ; for the axioelectric coupling of axion-like particles, values below are reached for particles with masses in the range of a few-hundred eV/ .
