Hollis - there are some good books about, but one of the important things about paganism is that there is no Book.
There are many models and systems within paganism, you'll have to find the one that resonates best with your own sensibilites.
At base, and at core, it is a Nature-centric religion/philosophy. Most pagans feel that Nature is sacred in and of itself. They then attempt to connect with that in any number of ways.
You OP was about the day to day practicalities - well there being no Book or dogma, that is largely up to you.
For some, it's about preparing and sharing food (the simplest and oldest form of alchemy). Others set aside some time eachday to pray or meditate; others yet try to make every chore into a prayer or an offering. Sex and relationships are another area where pagans focus their religion.
In many ways, it's exactly the same as any other religion or philosophical model for living, in that your sensibilites and beliefs inform your choices and decisions. Pagans will be aware and careful of environmental issues, for instance.
Most pagans celebrate the Circle of the Year, which is framed around the solar and seasonal "corners" or hinges of the annual cycle: Samhain, Winter Solstice, Imbolc, Vernal Equinox, Beltane, Summer Solstice, Lammas, Mabon Equinox, and back to Samhain.
Being in an urban environment makes it tricky to observe the the turning of the year, and most pagans will try to get out onto the land for extended periods, to celebrate at least one of these festivals. Many will find some way to live outdoors for the duration - camping or hiking. They'll gather at some sacred site (such as Stonehenge) and stay up all night to see in the dawn.
More and more, pagans are exploring their local sacred sites, since the big ones are now so crowded and issues of access and policing are becoming problematic.
And so on...
