"You being an Asian does not / don't know this"
Solution 1:
It may become more apparent if you move the 'you' to the other side of 'being an Asian,' making the sentence:
It's a shame that, being an Asian, you does not know this.
'You does' should become 'you do,' making the sentence:
It's a shame that, being an Asian, you do not know this."
Solution 2:
No. I think you want:
"it's a shame that you, being (an) Asian, do not (/don't) know this"
Solution 3:
Instead of 'being an Asian', the term 'as an Asian' might work well.
It’s a shame that as an Asian, you do not know this.
You'd probably be better off totally rearranging the sentence to make it clearer.
It's a shame that an Asian like you does not know this.
or
It's a shame that an Asian such as you does not know this.
