Are there any distinctive differences (or rather trends) between Western VS Eastern religions in how they were constructed/are practiced today?
I don't have a huge amount of experience with Eastern religions, so this is really just my impression, rather than an informed comparative religion thesis.
Islam is derived from Xianity, Xianity from Judaism, Judaism from earlier Canaanite and Mesopotamian religions.
Ditto the Eastern religions have taken from and been influenced by other Eastern religions. Concepts of karma, reincarnation, dharma, and "everything is one" all seem to be borrowed from each other across Hinduism, Buddhism, Taoism, Jainism, Shintoism, etc. While their adherents would disagree, there's not as much daylight in between their core concepts as they might like to think.
Abrahamism is somewhat unique in that it has consolidated all the various gods into a single deity who should be (but somehow is not) held responsible for everything, including all the randomness, inconsistency and unfairness in the world, where Eastern and the predecessors to Judaism, including Hellenism, had a whole pantheon of mercurial gods with their own domains and competing interests, priorities and relationships.
While the mythology of the polytheisms mostly plays out in some inaccessible godly realm, with the exception of the rebellion of Lucifer, Abrahamism plays out in the dusty, dirty, mortal human realm, where we can say that purported actions such as walking on water are idiotic and false.
Being set in our real world rather than Olympus or Takamagahara, and fleshing out the character list with humans - since heaven contains only the Abrahamic god and his remaining angel-slaves - Abrahamists have forgotten that their characters and mythology are fictional. They've confused characters such as Jesus, Moses, Abraham, etc, for literal historical figures. Whereas something like Hinduism is practically its own comic book superhero universe, and I don't think anyone is actually arguing about Historical Ganesh or Historical Inari Ōkami.
Across both Eastern and Western domains you've got a ton of magical thinking about how the world works, a lot of fixation on death and trying to imagine there's something after or beyond it in order to alleviate that fear, and a lot of superstition and unhealthy attitudes around virginity, sexual purity (for both men and women), and menstruation. In more modern times, Hinduism seems to have learned at the feet of Islam, and across the board, all these faith traditions are trying to pretend that their religion was right the whole time.
e.g. Muslims trying to pretend that the quran doesn't say that the Earth is flat and instead acting like "spread out" is a description of the oblate spheroid shape of the Earth; this gets worse when they try to insist it means "spread out" like an "ostrich egg".... which is a prolate spheroid, not oblate.
As religiosity across the whole population appears to be dropping, average religiosity among individuals who are left naturally rises, and there's a certain desperation at trying to remain relevant, especially as COVID has shown the futility of these beliefs in gaining protection or relief from it.
