Vowel /ɪ/ appears in its common spellings of <i>, <e> and <y>. Vowel /eɪ/ has a great many spellings included in this list, among them <aCe> as in drape, <ai> as in bait, <ei> in deign, <ay> in lays, the highly irregular <ao> in gaol, and in French loan words <et> as in bidet and <é> as in canapé. It is also there in the letters A and H.
Although this contrast is between a short vowel and a diphthong, it is potentially a problem for speakers of languages which do not have an [eɪ] diphthong and replace it with a mid front vowel. This is a known problem for some Arabic speakers and Swahili speakers.
In most cases the contrast is made in the stressed syllable, but where it is not I doubt whether the distinction is always consistent. Magnet/magnate are close to being homophones, and the same might be true of parky/parquet and Sunday/sundae.
The homograph gill appears in the pairs gill/Gael and gill/gaol, one for each pronunciation of <g>.
The only taboo word confusion is piss/pace.
