Question about Baphomet

Is Baphomet (Mendes) and Osiris in anyway connected...

I have a path where follow the Wiccan Tradition and Egyptian culture and I worship Aset as the Goddess and Baphomet as the God

I would say no, they are not related. We already know of Aset so I won't draw any parallels there.
Baphomet is the Goat of Mendes ans is of Islamic lore possibly traced back to the Yezidi tribe, but that is speculation on my part.

Though when we encounter Eliphas Levi's reinvented Baphomet we have something closer to what you are speaking of:

From Wikipedia:
Levi called his image “the Baphomet of Mendes”, presumably following Herodotus' account
that the god of Mendes — the Greek name for Djedet, Egypt — was
depicted with a goat's face and legs.

Herodotus relates how all male
goats were held in great reverence by the Mendesians, and how in his
time a woman publicly copulated with a goat.
However the deity that was venerated at Egyptian Mendes was actually a ram deity Banebdjed (literally Ba of the lord of djed, and titled "the Lord of Mendes"), who was the soul of Osiris. Levi combined the images of the Tarot of Marseilles Devil card and refigured the ram Banebdjed as a he-goat, further imagined by him as "copulator in Anep and inseminator in the district of Mendes".

Baphomet is a real entity that looks just like the picture and flies about. It's not something someone made up.

To a great extent the post by the banned forum member was accurate. To my knowledge, Dynastic Egypt did not have a goat god (corrections welcomed) and the reference to the "Goat of Mendes" was mistakenly to the ram god. Levi's anthromorphizing of many nineteenth century occult themes into his dipiction of Baphomet is just that, in my opinion. I would enjoy seeing references to an identical Baphomet that predates Levi's original publication.
