Vaet's influences included Nicolas Gombert, whose style of unbroken, smooth polyphony can be seen in most of Vaet's music; his friend Clemens non Papa; and Lassus, whose style he often imitated. Vaet used cross-relations to a degree rare at the time (though they are also significant in the music of Gombert), and they pungently spice contrapuntal passages; sometimes they are even simultaneous, resulting in dissonant clashes: no one would mistake his music for that of Palestrina, for this reason alone. Vaet also sometimes ended compositions on minor triads (for example the motet "Postquam consummati essent" – ending on a minor chord was very rare between the mid-sixteenth and mid-seventeenth centuries). Another peculiarity of his style was a liking for progressions based on the circle of fifths, as well as dominant-tonic cadences, both features which foreshadow the changes in music which were to come at the end of the century. His use of circle-of-fifths progressions may be an influence from Lassus; it is also a feature of Spanish polyphony of the period, and as a member of the chapel of Charles V, and later Maximilian II, he may have been familiar with the music of Spaniards such as Guerrero, who wrote in a similar idiom and also worked for Maximilian.
