There's no problem in saying {mayqel jIH}  "I am Michael"
Next, {SoH 'Iv} equals to {'Iv SoH}, both words can act as the verb.
ok, I came back..

if I write {'elaDya'ngan jIH}, this can only mean "I am (a) greek",
right ? So, how come if I write {mayqel jIH}, this can mean "I am
michael' ? even if we take into account, that klingon does not have
"a/the", then again the meaning can only mean "I am a michael".

A Klingon to-be sentence expresses the idea X = Y. 'elaDya'ngan jIH me = Greek; mayqel jIH me = Michael. There is no a, an, or the in Klingon.
as I understand , the subject is defined as "one who is, or one who
does" ; and since we use OVS, then how can we place the "one who is,
or one who does", before the verb ?

A Klingon to-be sentence is not of the form object-verb-subject. You should more or less ignore the ideas of subject and object with regard to to-be sentences.
