Q: Does the Buddha ever mention the term manasikara in his mindfulness instructions?
A:Not that I know of. The term figures most prominently in Abhidhamma-based treatises on Buddhist psychology. In the Buddha’s practical instructions on both samatha (tranquility meditation) and vipassana (insight meditation), the terms sati and sampajanna appear most often.
And from the words of the Buddha's "How appropriate attention (yoniso manasikara) leads to stream entry:" SN 22.122
