"Wast a par with" is not a common phrase and therefore does not have a standardized spelling. However, it can be phonetically transcribed as /wɑst ə pær wɪð/. The first word "wast" is spelled with an "a" instead of an "e" due to its archaic past tense form. "A par with" is spelled as expected, with the "a" sound in "par" and the "i" sound in "with" transcribed as /pær wɪð/.
