You can query the msdb backupset table for this kind of information:

SELECT 
    database_name,
    recovery_model, 
    CASE bs.type 
        WHEN 'D' THEN 'FULL'
        WHEN 'I' THEN 'DIFFERENTIAL'
        WHEN 'L' THEN 'TRANSACTION LOG'
        ELSE 'UNKNOWN'
    END AS backup_type, 
    backup_finish_date,
    backup_size,
    compressed_backup_size
FROM msdb.dbo.backupset bs

EDIT:

This query will return the database name, recovery model, and the last datetime for full, differential, and log backups. If a database returns NULL for the last FULL it is not being backed up at all. If it returns NULL for the last transaction log and the database uses FULL recovery it is not being backed up correctly.

SELECT  
    d.name, 
    d.recovery_model_desc,
    MAX(CASE bs.type WHEN 'D' THEN backup_finish_date ELSE NULL END) AS [last_full_backup_date],
    MAX(CASE bs.type WHEN 'I' THEN backup_finish_date ELSE NULL END) AS [last_diff_backup_date],
    MAX(CASE bs.type WHEN 'L' THEN backup_finish_date ELSE NULL END) AS [last_tlog_backup_date]
FROM sys.databases d
LEFT JOIN msdb.dbo.backupset bs ON bs.database_name = d.name
GROUP BY d.name, d.recovery_model_desc
