The exported function should take a *zap.Logger, since that's what all of zap's public APIs return.

return &Logger{logger: logger}
}

// Error logs a message at error priority
func (l *Logger) Error(msg string) {
l.logger.Error(msg)
}

// Infof logs a message at info priority
func (l *Logger) Infof(msg string, args ...interface{}) {
l.logger.Info(fmt.Sprintf(msg, args))

Please first check if Info is enabled, since we don't always want to incur the overhead of string formatting:

if l.logger.Facility().Enabled(zap.InfoLevel) {
  l.logger.Info(fmt.Sprintf(msg, args))
}

In general, if you're going to do formatted logging, you're better off wrapping *zap.SugaredLogger, which already has an efficient version of this API. Accepting that type also makes it clear to users that you're planning to do printf-style logging. Every *zap.Logger can easily and cheaply be converted to a *zap.SugaredLogger.
