I personally do not think that participation in ritual and cultural practices is a necessity for being a Hindu. They are widely varied and region-specific anyways..and over time new ones may grow that are more at home in Western cultures. If a specific theological/philosophical worldview and modes of living within the Hindu thought appeals to you so that you feel fulfilled in adopting it to your life situation, then you are living within Hinduism.I'm not sure if anything can be done, at least by anyone but me.
As I've said previously in different threads here, I feel that self-identifying with a religion but not participating in rituals and practices or not worshiping their deities as other followers/devotees do, even though I share the same worldview, would be an affront to them.
Then again, it very well could be my experiences with more dogmatic religions that led me to this mindset.
My sense has been that people who feel ideas in Hinduism appealing feel a lack of clarity and confidence regarding how to extract the things they want from the extreme complexity of this tradition and use it in their day-to-day lives. If this is something you (and others) have a difficulty with, then maybe we can help out a bit in a seperate discussion thread.
