I've configured IOS as instructed:
address-family ipv6
neighbor 2001:490:F00:A::2 activate
neighbor 2001:490:F00:A::2 send-community
neighbor 2001:490:F00:A::2 route-map OMALAN out
exit-address-family
ipv6 prefix-list LAN seq 5 permit 2001:490:F00:3::/64
ipv6 prefix-list LAN seq 100 permit 2001:490:F00::/48 le 64
ipv6 prefix-list LAN seq 200 permit 2001:490::/32
route-map OMALAN permit 10
match ipv6 address prefix-list LAN
But I still can't make the router to advertise the routes defined by prfix-list and route-map:
Spore#sh bgp ipv6 unicast neighbors 2001:490:f00:a::2

Seems that the only way to advertise NLRI is the network statement. Is there limitations regarding to the train or feature set. Currently running 12.3.7T provider feature set.
The networks are either connected or statically pointing to null0 interface.

Sorry about this!
The routes have to be in BGPtable before they can be filtered. After adding them with network statement to local router's BGP table I can manipulate advertisements with prefix-lists as I want.
Example to advertise only /32
address-family ipv6
neighbor 2001:490:F00:A::2 activate
neighbor 2001:490:F00:A::2 send-community
neighbor 2001:490:F00:A::2 route-map OMALAN out
network 2001:490::/32
network 2001:490:F00:3::/64
exit-address-family
ipv6 prefix-list LAN seq 200 permit 2001:490::/32
route-map OMALAN permit 10
match ipv6 address prefix-list LAN
