Do some guided meditations (You can find these on youtube) and do some divination to see where it leads.
Also, Vat, the Goddess is a really ambiguous answer - which Goddess? Diana, Selene, Bastet, Epona, Hecate, Mama Killa, Phoebe, Bendis, Hina? etc and what about Gods of the Moon? such as Marama, Fati, Avatea, Thoth, Osiris etc? (apologies to practitioners if I have butcthered the spelling or the correct titles of the Deities in question)
One thing to consider is that the moon is always there, and the phase is only a measurement of how much of the sun's light we can see bouncing off of it. Someone who doesn't rely heavily on symbolism and representation can technically still connect to 'full moon' energies at any time if they want to. It is just more difficult because it takes conscious effort to shift one's natural perspective.
Different phases also call to different people. It is common for people to connect with the full moon because it provides the most light during the darkness of night, giving a sense of security or favor. But there are also people who connect and energize more strongly from the new-moon, and the idea of the dark night and safety or peace through shadows. It may be that you just connect well with the new-moon and the energies it tends to represent.
Bast/Bastet (the -et is really unnecessary in most transliterations) is not really a Kemetic "Moon Deity". She's more aptly a solar one as an Eye of Ra and it's really not until the Greeks take over that She gets a Moon aspect. This is because the Greeks compared Her to Artemis as being one in the same. Which is why Heru-sa-Aset is sometimes called Her brother; because He is supposed to be Apollo.
Thoth/Djehuti is a very involved moon Deity, but Osiris/Wesir is not really a "Moon Deity", a "Deity of the Moon", etc. So far as I know, not even in later times does He have a close connection with the Moon, however many of the modern practitioners associate Him with it. (Our Moon is related to male, not so much female until the Greeks took over.)
Iah is literally the Moon Deity as He is the literal personification of the Moon, like the Aten is ghee literal personification of the Sun. There's also Sokar who gets some New Moon influences, and a form of Heru called Heru-Khenty-irty (Horus foremost of eyesight) or Heru-Khenty-en-dirty (Horus foremost without eyesight) which references His eyes as being the Sun and Moon. Set and Heru-sa-Aset are, to a lesser degree, attributed with the birth of the Moon, but it's Djehuti that really makes it happen.
There are, of course, other references, but for practical purposes, let's just say there's a lot of Men. Shiny, Moon Men. Lol.
